The MontBell pillow I suggested is the red one , top right end side.
You can blow up the Flexair without the straw, just separate the plastic ends and blow inside. I use my long handle spoon to deflate it, but you could use a peg as well.
As you can see I have made mine out of wine cask bladders and water wings, however the Flexair and the MontBell are more comfortable for me.
These are the pillows that have passed the test, many others (failed experiments or too heavy/bulky) have been given away or become land fill.
One that I still used last year and not in the picture is the stuff sack filled with clothing, we all have one of those. Not that comfortable for me but doable.
As pointed out in a different thread, I thought that I had a problem with tents, jackets and mats but apparently I am well rounded nerd.
